This Melchizedek was a king of the city of Salem and also a priest of God Most High. When Abraham was returning home after winning a great battle against the kings, Melchizedek met him and blessed him. Then Abraham took a tenth of all he had captured in battle and gave it to Melchizedek. The name Melchizedek means “king of justice” and king of Salem means “king of peace.: There is no record of his father or mother or any of his ancestors – no beginning or end to his life. He remains a priest forever, resembling the Son of God.
Consider then how great this Melchizedek was. Even Abraham, the great patriarch of Israel, recognized this by giving him a tenth of what he had taken in battle. Now the law of Moses required that the priests, who are descendants of Levi, must collect a tithe from the rest of the people of Israel who are also a descendant of Abraham. But Melchizedek, who was not a descendant of Levi, collected a tenth from Abraham. And Melchizedek placed a blessing upon Abraham, the one who had already received the promises of God. And without question, the person who has the power to give a blessing is greater than the one who is blessed. (vv. 1-7, NLT)
